ELECTRIC SIGNAL.

SPECTFICATIO N forming part of Letters Patent No. 754,208, dated March 8, 1904.

Application filed April 24, 1902. Serial No. 104.506. (N model.)

To all whom it may concern.-

Be it known that I, JOSEPH E. FELLER, a citi- Zen of the United States; and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Electric Signals, of which the following is a full, clear, and exact description.

My invention relates to electric signals suitable for general use, and more particularly to a type of instrument in which the person signaled may indicate to the person signaling if the signal is properly received.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a diagram showing two stations each equipped with a transmitter and receiver. Fig.1 is a fragmentary diagram showing my system as used wit'ha single transmitter and a single receiver. -Fig. 2 is a side elevation of one of the receivers. Fig.

3 is a front elevation of the same. Fi 4 1s a plan view of one of the transmitters. Flg. 5

is a vertical central section through the same.- Figs. 6 and 7 are fragmentary detail views showing the contacts of the transmitter, and Fig. 8 is a fragmentary detail view of one of the signal-dials used upon the receiver.

A and B represent the respective transmitter and receiver used at one of the stations, while 0 and D represent the respective transmitter and receiver used at the other station. A source 1 of electric-current supply is connected by wires 2 3 with wires 4 5, leading to the transmitters A (J, located at the respective stations. Movable arms 6 7 are connected,respectively,with the wires 4 5. These arms are free to move over the sector-shaped contacts 8 9, which are provided with distinguishing ordinals, as shown. wire 10 11 12 and 13 14 15 areprovided upon the respective transmitters. These rings are connected with the sector-shaped contacts by means of wires 16 17 18 19 20 21, as indicated more clearly in Fig. 1. These rings are also connected, by means of wires 22 23 24 25 26 27 with the, circuit-wires 28 29 30. wires 2 3 are connected, by means of wires 31 Closed rings of The 32 with the respective motor-fields 33 34 of the receivers. These fields are connected with the brushes 35 36 and through these brushes with the collector-rings F G, which latter are connected by wires 37 and 38 with the receivers B and D. The wires 2 3 form a triple c0nnection with the coils 39 4O 41 of the receiver B and the coils 42 43 44 of the receiver D." The circuit-wires 28 29 30 are connected with the brushes 45 46 47 of the receiver B and with the brushes 48 49 50 of the receiver D. The three brushes of the receiver B, just mentioned, are,connected, by means of collectorrings a I) 0 and wires 5152 53, with the respective coils 39 4O 41, which serve to ener-- gize the respective poles a b 0 of receiver B. The brushes 48 49 5.0 of the receiver D are by means of the collector-rings d e f and wires 54 55 56 connected with the respective coils. 42 43 44, which are provided for the purpose of energizing the respective poles d a f of the armature of the receiver D. 'By this arrangementthe coils 39 40 41 42 43 44 are renderedto some extent independent of each other;

The two receiving instruments at the two stations are substantially alike, and this isalso true of the transmitters. The transmitter A comprises a disk A, of insulating material,provided centrally with a pivot A, having a finger-piece A An insulating-sleeve A for the; pivot A is surrounded by a bearing A and upon this bearing is mounted an arm At, provided with an insulating-sleeve A and free to turn upon the pivot A An insulating-block A normally prevents electrical communica tion between the arm 6 and the sectors 8. (See Figs. 4 and 5.) A roller A, of conducting material, is mounted upon the stem A con nected to'the block A", and is revoluble, respectively, to other parts. When the arm 6 is moved circularly over the sectors, the roller. A is brought into contact with each of the sectors successively. By this means each time the roller A passes over a sector, as indicated in Fig. 7, a metallic connection is momentarily formed between the sector and the arm 6 through the roller A". Limiting-stops 57 58 are provided upon the transmitters for the purpose of preventing the arm from moving beyond predetermined points. (See Figs. 1

and 4.) The arms of the transmitters may be made to move clockwise, as indicated in Fig. 4 and the lower left-hand portion of Fig. 1, or counter-clockwise, as in the lower righthand corner of Fig. 1, as desired. When the arm moves clockwise, the ordinals may be of the form shown in the left-hand portion of Fig. 1 and in Fig. 4, whereas if the arms move counterrclockwise the ordinals may have the form indicated in the lower right-hand portion ofFig. 1 and in Fig. 8. The direction of motion of the arm is therefore immaterial.

The receiver D is provided with two poles D D which are excited by the field 34, as above described. These poles are provided with convex faces I), close to which the poles (1 I) 0 of the armature are free to revolve. Rigidly connected with the armature is a gearwheel '1), in mesh with the teeth on a dialwheel D The dial-wheel is provided with a circle of ordinals D which are free to move relatively to a stationary pointer D The receiver Bis similarly constructed; but, as above explained, the ordinals and the arm 7 may be arranged counter-clockwise, as indicated in the drawings, as desired.

The operation of my device is as follows Supposing the operator at one of the stations desires to signal the operator at the other station and desires to learn whether the secondmentioned operator has received the signal and, if so,whether or not he has received it correctly, the signaling operator moves the arm 6 around, say, to the sector, which is shown in the drawings as provided with the ordinal 5. In doing this the arm 6 passes successively over the first five of the sector-shaped contacts, completing the circuit through the said contacts separately and individually. When the arm 6 moves from the dead sector 59 through the sector provided with the ordinal 1, the circuit is as follows: from the source of electricity 1, through wires 2 and a, arm 6, sector numbered 1, wire 16, ring 10, wire 22, wire 28, brush 48, wire 54, coil 42, wire 38, brush 36, field-coil 34c, wire 32, and wire 3, back to the source. When the arm 6 touches the contact provided with the ordinal 2, the circuit is as follows: source of electricity 1, wires2and 1, arm 6, sector numbered 2, ring 11, wires 23 and 29, brush e9, wire 55, armature-coil 13, wire 38, brush 36, field-coil 3%, wires 32 and 3, back to the source. The two circuits just traced have the effect of separately energizing the armature-poles (i and e of the receiver 1), thus causing each of the poles mentioned to carry the armature onethird of a revolution. The contact 3 next being encountered completes the following circuit: The source of electricity 1, wires 2 and 4:, arm 6, sector numbered 3, ring 12, wires 2e and30, brush 50, wire 56, coil 14:, wire 33, brush 36, field-coil 3e, and wires 32 and back to the source. The arm being carried farther, so that the roller encounters the see- I other operator,

tor numbered 4:, the circuit is substantially the same as when it encountered the sector numbered 1, for the reason that sector numbered 1 has practically the same connections as sector numbered 1. The arm being moved still farther, so that the roller A encounters sector numbered 5, the circuit is again completed in substantially the same manner as when the roller encountered sector numbered 2. It will therefore be seen that when the arm 6 is moved over a given number of sectors the poles (Z 0 f, each rotating the armature one-third of a revolution, will cause an aggregate amount of rotation in the armature corresponding to the aggregate number of sectors brought successively into the circuit by means of the arm 6-that is to say, if the arm 6 be moved from one sector to another, the armature of the receiver 1) will move the dial-wheel D a corresponding distance, so that the stationary pointer 1) will indicate to the operator signaled that the signaling operator has moved his arm 6 to the first live sector. 1f the arm 6 be moved to any other sectorsay to the one numbered 11 the dial D will also rotate until it stops with H its number 11 ad acent to the pointer. The operator who is signaled and who of course is in charge of the instruments C and B now turns his arm 7 to that sector corresponding to the one indicated by his dial. If his dial shows ,say, the numeral 1 or 5 or 13, he turns his arm 7 to the sector numbered 1 or 5 or 13, as the case may be. The result is that the dial-wheel upon the transmitter B rotates until the pointer stands adjacent to the numeral 1, 5, or 13, as the case may be, upon the dial. Of course these members are arbitrarily selected as examples for the purpose of illustrating the principle. it will be noticed that by tracing the circuits upon Fig. 1 the movements of the arm 7do not affect thereceiver D, but that they do affect the receiver B. The circuits may be traced from the source of supply 1 through the several armature-coils of the receiver B and will be found to correspond exactly with those already traced from transmitter-A through receiver 1). F or instance, ifarm 7 be moved upon'the sector numbered 1 of the transmitter C, the circuit is as follows: from the source of electricity 1, through the wires 3 and 5, arm 7, sectornumbered 1,wire 19, ring 13, wires 27 and 23, brush 15, wire 51, armature-coil 39, wire 37, brush 35, field-coil 33, wire 31, wire 2, back to the source. The ether circuits may be traced successively,,as above indicated, with reference to the use of transmitter A and receiver 1). it will be noticed, therefore, that either operator can use his own transmitter to actuate the receiver of the but is unable to actuate his own receiver. It is the duty of either operator upon being signaled to answer the signal, so as to indicate to the signaling operator ately moved back to. the starting-point after each signal. By this means the instruments are corrected, as .it were, after each successive use-that is to say, if through accident the arm should pass over one of the sectors without completing the circuit or if some unthe dials or with any part of the apparatus,

so as to prevent exact correspondence between the respective receivers and transmitters at the different-stations, the movements of the respective arms 6 7 back to the dead sectors 59 60 cause both transmitters and receivers to start from a common point or its equivalent. By this means any disparity that may occur between the receiver and a trans mitter actuating it will be removed before the instruments are used again.

It will be noted that while the arm of the transmitter and the armature of the receiver each move with a step-by-step motion and while the dial moves synchronously with the arm, yet the number of revolutions of the armature have no relation to the number of movements of the arm. The arm in moving over six sectors does not make half of a complete revolution, yet during this movement the armature makes two complete revolutions. Of course any number of sectors may be employed.

I do not limit myself to the apparatus described above or to any particular apparatus,

as the mechanism for carrying out my invention may be varied considerably without departing from the scope of my invention. The above description is mere] intended to show the application of my in ention to one particular form of device.

If desired, a single set of instruments may be used, as indicated in Fig. 1. From the source of electric current 61 a wire 62 leads to the arm 63, which moves over sectors 64, substantiaily as described above. The sectors are connected with the rings 65 66 67, and these rings are connected by wires 68 69 70 with brushes 71 7 2 7 3, resting upon collectorrings 7 4: 75 76. The collector-rings are connected by wires 77 78 79 with coils 8O 81 82 upon cores r s t. A return-wire 83 is connected with the collector-ring 84, and thereby with the brush 85, and this brush is connected by the wire 86 with the field-coil 87. From the field-coilthe wire 88 leads back to the In this way mistakes may be substantially the same as those already de: scribed and may be readily traced.

My inventionmay be used in various relations. '8 It might be advantageously employed, for instance, in a structure such as the Brooklyn bridge, where it frequently happens that an oflicer located upon one part of the bridge desires to signal an engineer or other operative or officer located upon another part of the bridge. ,The invention might also be used to advantage in hotelsand in connection with block-signalsof railways. It is impossible, however, to enumerate the many diversified ways in which my invention may be used, and 1 therefore make no attempt to do so in this specification. The scope of my invention is pointed out in the followingclaims. authorized person should tamper with one of Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
